Avoid Ofna/Jammin/Hobo like the plague! For any class.
The Slash 4x4 looks like the one to get. I've seen some incredable moves performed by a few Slashes running 1/8th scale motor/esc's and 1/8th scale shocks.
Heard the D8 shocks fit.
I'd get a Slash 4x4, but I just pulled the trigger on a new Truggy build.
